Great article. Glad to see the 555 right at the top where it belongs. Surprised there were no PLL chips on there though! There were also no DDS sythesizers...but there was the function generator, an early model.

My all-around favorite was the MC1496....don't know how many radio circuits I designed around that old battle axe!

Odd list. Where are the voltage regulators? Why doesn't the Intel 4004 get in as as the first microprocessor, and where is the first 4 banger calculator chip, not to mention the HP scientific calculator chip?
